G'day John (@johnb),
The under-surface looks good to me.
It will probably blend together a bit more when you add clear coats anyway.
On the top surface colours - I seem to recall that being an early series aircraft, this one may have been in the mid-war greys.
I'd have to search my references to be sure...
Either way, it is great to build the mounts of legendary pilots.
Looking forward to more progress.
